virt-v2v/0002-i-libvirt-print-URI-without-connecting-RHBZ-1839917.patch
Richard W.M. Jones 2f9214744a Reapply patches since we are using git format-patch --submodule=diff 
- Don't comment out patch 0029 (the common submodule update).

- Use a common/.gitattributes trick to exclude files from the common
  patch that are not included in virt-v2v tarball.  This also requires
  some sed hacking.

NB: I tried using ':(exclude)...' stuff and it does not work for
submodules, at least not with the git version in RHEL 8.

For more info see private email thread "Customer case requiring our
assistance" in 2023.

Subject: [PATCH] -i libvirt: print URI without connecting (RHBZ#1839917)
Pass (again) around the libvirt URI string in the various input_libvirt
subclasses so that input_libvirt#as_options does not need to connect to
print the connection URI.
As related change: pass input_conn as non-optional string parameter in
classes that require one (all but input_libvirt_other, basically). This
avoids the need for extra checks.
(cherry picked from commit 86d87563ee03e86ca9abdcad4f674af66a883006)
